European Alternatives to Microsoft Authenticator
Free authentication app from Microsoft providing secure two-factor verification, passwordless sign-in, and passkey management for Microsoft and third-party accounts.

Why leave Microsoft Authenticator?

- A Dutch impact assessment reveals Microsoft Office collects 23,000 to 25,000 types of events about users without transparency.
